Hi all, I am interested in interval arithmetic. Does anyone know something about haskell implementations in this domain? It would be nice to have a datatype Interval with the elementary operations {+,-,*,/}, where
+ :: Intervall -> Intervall -> Intervall (a,b) + (c,d) = (a+c,b+d)
- :: Intervall -> Intervall -> Intervall (a,b) - (c,d) = (a-d,b-c)
etc. Bye Jonas
